SHIP-BUILDING PLANT.

SPECIFICATION forming part of Letters Eatent No. 747,782, dated December 22, 1903. Application led October 28, 1901. Serial No. 80,266. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN WEIGHT SEAvEE, a citizen of the United States, and a resident of Cleveland, Ohio,'have invented certain lm-v cranes for handling the material used in theA construction of the ship.

In the accompanying drawings, Figure l is a transverse section of a ship-building plant constructed in accordance with myinvention,

and Fig. 2 is a similar view illustrating an-v other method of carrying out my invention.

The structure shown .inFig. 1 comprises opposite longitudinal rows of vertical beams or columns having the spaces between the same suitably filled. in, so as to constitute the opposite Walls 1 of a shop which has rooftrusses 2, projecting on -each side beyond the sides of the roof, as shown at 3, so as to form trusses for the support of cranes 4, there being in the present instance two cranes disposed end to end on each of the projecting trusses 3, although but a single crane can be' carried by eachof said trusses, if desired.

The central inclosed portion of the structure constitutes a shop which may contain.

. for the reception of light machinery, such as Woodworking-tools and the like.

When the central structure has consider` able span, a central row of columns 10 may be employed to support the door 6, as shown in Fig. 1, and also to support the innerrunways of cranes 1l, with which the shop is provided, a single crane being used when the central row of columns is not employed.

The walls 1 have suitable windows 12 for properly lighting the shops, and forthe same purpose the roof has a central skylight 13, and the oor 6 has a central skylight 14, and

at desired intervals the walls l may be proy vided with openings normally closed by slid! ing doors 15, so that material canhbe removed from the shop at the most convenient point.

`On each side of the shop inV the spaces overhang by the projecting roof-trusses 3` are the ship-building ways, the columns constituting part of the Walls ofthe Shop being, if desired, utilized for the support of gangways or scaffolding 16.

In that form of myvinvention illustrated in Fig. 2 the intermediate floor 6 is dispensed Witll, the shop having` but a single story and V a single crane 17 being employed instead of the two cranes 11, as shown in Fig. 1.

In a ship-building plant constructed in acv cordauce with my invention all of the ground area is effectively utilized, and the machines whereby plates and other parts of the ship structure are prepared for use bear such relation lo the ship-building ways that the parts can be handled With a minimum expenditure of time and labor, and consequently atl the least expense,the trusses 2 serving the double purpose of roof-trusses for the shop and supports for the cranes which serve the ways.

'Hence the structu re is most economical, since the use of a central supporting structure for vthe crane-trusses is necessary in any case,

and by my invention the erection of a separate shop for the punching, shearing, and other preparatory machinery is rendered unnecessary.

If desired, the roof-trussesI may project beyond the shop on one side only, so as to serve ICO jecting beyond said inclosu re, tracks supported by the projecting portions of the trusses and extending at right angles to the planes of said trusses, and a crane constructed to operate ou said tracks, substantially as described.

2. Thecombination iu aship-building plant, of an inclosed structure having a series of trusses for supporting the roof thereof, each of said trusses having portions extending on both sides of the iu'clos'ed structure, tracks supported by the projecting portions of the truss, other tracks supported on the outside of the Wall-supporting framework of the inclosed structure and cranes constructed to operate upon the tracks, said tracks extending at right angles to the planes of the trusses, substantially as described.

3. The combination in aship-building plant, of an inclosed structure having Walls and a roof, With a series of substantially parallel trusses for supporting said roof, said trusses having portions extending outside of the inclosed structure, three tracks supported from the under side of said extended portions of the trusses, one of the same being adjacent to the outer ends thereof and the others being carried at substantially the middle portions of said trusses, with a track supported on the outside of the wall-supporting framework of the inc'losed structure, and cranes operative upon said tracks and movable in lines at right angles to the planes of the trusses, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
